FEEDING DEVICE FOR METAL-WORKING MACHINES.-

SPECIFICATION forming part of Letters Patent No. 700,325 dated'lvlay 20, 1902.

Application filed May 14, 1901. Serial No. 60,230. demote.

To all whom it mat concern:

Be it known that I, THOMAS S. HALEY, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented"cer-' tain new and useful Improvements in Feeding Devices for Metal-Working'Machines, of p ernediby thispart ofthe apparatus. The form. of agitator which I have illustrated con which the following is a specification.

My invention has for its objectio produce mechanism of the class described having points of novelty and advantage.

In the drawings I have shown my invention adapted for use for feeding wires to a relation to a set of dies forforminga buckletooth. Fig. 2'is a front view of the device embodying myinvention. Fig. 3 is a side view of the same, showing the operating mechanism for the, agitator.v Fig. 4 is. a view similar to Fig. 3, but with parts broken away,

showing the diiferent positions of the operating mechanism for the agitator. Fig. 5 is a front view of the same, showing details of construction.

In buckle-making machinery it is a common practice to cut the wire from which the buckle is made into proper lengths, and these pieces are then fed to the operating-dies. My

Vice and at the opposite side is arranged a reciprocating-head M, carrying a plunger L, which is adapted to push the wire from the chute into the die. In the ordinary operation of the device the chute C and the hopper are kept full, and as fast as one wire is removed from the chute at the bottom another drops into the chute at the top, keeping it continually filled. It has been found, however, in practice that the wires become jammed at the narrow outlet at the bottom of the hopper, so that they do not drop into the chute,

base J, as by means of the bolts j.

and the practically continuous operation of the machine is thus interfered with. To obviate this difficulty, I provide an agitator to keep the wires in the hopper in. motion, so-

that there is no danger of their becoming jammed, and the uninterrupted operation of :.th'e machine is insured so far as it is 'govsists of one or morefingers E,-projecting into ,the chute through openings in oneof its walls, and said fingers-are secured to a'shaft' F, jo\ 1rnaled as at ,1on the exterior, -This shaft is kept in-practically continuousvibra tion, andthe fingers moving with the shaft come in contact with the wires at the-bottom ofthehopper. Every timethefingers strike the wires theylmove them, and prevent them from jamming at thesmall outlet from the hopper intothe chute 0, thus insuring a continual feed from the hopper to the slot. A

simple form of ,mechanism for vibrating the shaftF is shown in the drawings. It consists of a lever G, secured to the shaft and weighted at its free end g. w This lever is connected, as by a spring h, with the intermittently-moving arm II. This device has been found in practice to keep the lever G and the shaft F in practically continuous vibration'and to operatein a verysatisfact'ory manner. Figs. 3 and 4 of the drawings show clearly the operation of this agitator. I also provide means for varying the length of the chute C, which consists of the ends Ladjustably secured to the Secured to the top of tl 0 ends of the chute are the plates K-for gui ing the wires into the chute. The end of the chute next to the operatingdies, through which the wires are pushed by the reciprocating plunger M, is provided with a pivoted guard-plate N, normally held in the per narrowed at the bottom, a substantially.

vertical chute forming a continuation of the hopper-mouth, a shaft journaled on the hopper, aweighted arm for causing said shaft to Ice turn normally in one direction, means forintermittently raising said arm, and fingers secured to said shaft and adapted to normally interrupt the opening from the hopper into the chute.

2. In a device of the class specified, the combination with the hopper, a shaft journaled thereon, and fingers secured to said shaft and adapted to be brought into contact with the contents of the hopper, of means for causing said shaft to oscillate comprising a Weighted lever secured to said shaft and a spring connection between said lever and a superimposed intermittently-moving member.

In a device of the class specified, the hopper narrowed at the bottom and opening into a substantially vertical chute, means for periodically interrupting the opening from the hopper to the chute, a plunger adapted to move lengthwise of the chute at the bottom thereof, and a spring-actuated guard-plate normally closing the end of the chute oppo site the plunger, substantially as described.
